Cross-slide of lathes of the turret type.



CROSS-SLDE DE LATHS GF THETURRErl Application nieu mich as, isis.

To all 'iw/iam it may concern e it knownV that l, HERBERT iius'rin, :isubject of the King of Great Britain, and residing at Bromsgrove, in thecounty of Worcester, England, engineer, here invented 'certain new anduseful improvements Relating to the Cross-Slides of Lathes ot the TurretType, of wiieh the following is e specification;

This invention relates to means of travers ing, transversely of the hed,e cross-slide of a :latheof the turret type, having inview moreparticularly ineens for such purpose which will traverse the cross-slidein a di'- rection at.' other desired angles to the lathe axis besidessimply at right angles thereto.

In order that the invention may he clearly understood, I will nowdescribe a convenient practical application thereof, which isillustratedloy the drawings herewith.

Of the'drawingsz-Figure 1 is a. trans verse section through a portion ofone side of the` lathe bed, showingfa side view' of the crossslide andthe saddle which carries it. Fig.` 2 is an outer view of the saddle andcrossfslide shown 'hy Fig. l, end shows also, in side View the forwardend et the turretsaddle and a portion of the turret. Fig. 3 is a planview of the cross-slide and saddle and of a portion of the forward endor' the turretfsaddle sind a portion of the turret.A

Fig. 5 is ,a section, to an enlarged-scale, of the saddle andcross-slide, taken on line of Fig. l, and Fie.

A worm-wheel isfixed to the spindle D, oonveniently in position, as shown, immediatelyabove the bevel wheel d. A horizontalv shaft F, which is slidablyjournaled within the saddle A` is formed with a worm f which meshes withthe teeth of the worrnwheel f. The shaft F is moved 'endwise by theturret saddle G coming against the end thereof during an advancemovement in each cycle of operations, and the endwise movement of theshaft thus produced in relation to the saddle causes it to act as :irack in relation to the worm-wheel f and turn such wheel, andconsequently the ver t-ieal spindle D, and move the slide B inward tothel work. As it will usually be required that some of the forwardmovements of the saddle G shall be inoperative in relation to the shaftF, an opening g is formed in the saddle, which passes over the end ofthe shaft F for each forward movement of the saddle which is required tobe inoperative in relation to the shaft. For

each forward movement of the saddle, however, which is required to beoperative in relation to the shaft, the free and thickened end L of anarm'h which is pivoted to the saddle is brought across the opening, anditself comes against the end of the shaft F during the forward movementof the saddle and moves the shaft as required. This arm is operated bythe turret H during a turning movement of its cycle of operations, andfor this purpose a pin 7c, which is screwed down through a lug 1 of theturret, presses down, against thc force of a spiral springe,l 7a2, aplunger Z which is slidably fitted "within a hole of the turret saddle,and thel plunger Ai has a cross pin lo* which engages with a slot of aportion of the arm /t which Y extends rearward of the pivot axis of thearm. In Fig. 4 an arm 7L is shown both at the right-hand and left-handsides' oli' the.A lathe, one of them beingT tor 4use in eonueo' tionwith a cross-slide which is mounted vat the right-hand side of thelathe. and the other for use in connection with a cross slide which ismounted at the other side of the lathe, providing that cross-slides arereuired at both sides of lthe lathe. 'l' he arm /L at the left-hand sideof the lathe is shown in its downward position clear of thecorresponding opening'g of the saddle, and the arm at the right-handside of the lathe is shown to have been moved up by the :1ction of thepin L, into position with its thickened end L across the correspondingopening g. The pin r: is carried in such pof sition in the turret H thatit operates the arm .to bring it into position across the opening g justas the turret is completing its turning movement which brings the pin cover the plunger 7.13, and the piu remains over the plunger la, holdingit. down,

while the turret then remains at rest inrelation to the turret-saddle.The head of the plunger 7c3 is rounded or slanted to en-l able the pin7c to move over it'and press it down as it does so, and the cross pinle* of the plunger operates within a vertical slot of the turret saddle,the upper end of which forms a stop to thev upward movement of theplunger. Through the lug la of the turf` ret is shown to be screwed asecond pin 7a" corresponding to the pin 7c, for the purpose of pressingdownv a. plunger for bit-inging;` a lever at the other side of the latheinto positionacross an openinggof the saddle,

in a case in which it is required tohav'e cross-slide at each side ofthe lathe'.A Both the pins 'c and 7c* may beserewed suilieientlyithrough the lug 1 to insure that they wilhy respectively, press down inturnv the plun-'V` gers for the respective levers, or either rof themonly may be screwed through. sufliciently for the purpose of pressingdown the respective plunger, or both of them may be slackened backsutliciently/ to insure. that neither plunger will be pressed' down. Asa matter of fact, in the arrangementshown, each pin 7c, Zyl, would pressdown each plunger, but either plunger would return, after being presseddown by the .pin

operate the cross-slide both outward and inn.

ward through the medium ofthe shaft the pin, which is carried by theturret i pr'- respect vof such worm shaft, is screwed haelt?" to insurethat at every forward movement of the turretsaddle the hole g will pass.over the end of the shaft F. The worm shaft* F can be removedaltogether if it is re` quired to operate the slide entirely through i'the medium ofthe shaft E. Y

According to'convenient means for efn. *e
